Zverev is the best I've seen. I don't think Djokovic's age can be an excuse. This is the best he's ever played in his career and he didn't win a set in the final. Diamond Age Initiated.I thought only Fed fans were using age as an "excuse" ...
Same as with Federer, we can't forget that Djokovic is no longer in the prime age for a tennis player, and he is likely to have some lapses in some matches, just as Fed had around this age. This was only one match, but even if Novak did start to lose to Zverev (or someone else) more often, it does not mean that he would have lost to them in their prime.
Anyway, this shouldn't be about Novak. Well done to Sascha. He has won three MS and a WTF now, which is a lot more than anyone else currently under the age of 30. Hopefully he will start to make a move at the slams now under Lendl's tutelage.

Until the AO 2019 which Djokovic will win.
